AXLE-LUBRICATO R.

SPECIFICATION forming part of Letters Patent No. 303,283, dated August 12, 1884.

(No model.)

To all whom it may concern.-

Be it known that I, ALBERT '1). Honor, a citizen of the United States, residing at Cos hocton, in the county of Ooshocton and State of Ohio, have invented a new and useful Axle Lubi-icator, .of which the following is a specification, reference being had. to the accompanying drawings.

My invention relates to axle-boxes, and to that class shown and described in Letters Patent No. 280,826, granted to n1e'July 10, 1883; and it has for its object to improvethe details of construction of the same.

The invention consists in the improved construction an d combination of parts hereinafter fully described, and pointed out in the claim.

In the drawings, Figure 1 is a perspective view of my improvement. Fig. 2 is alongitudinal section of the same, and Fi 3 is a transverse section on the line w .r of Fig. 2.

A represents the spindle, which is formed with a straight longitudinal groove, B, and

with a'screw-threaded end, 0, having ashonlder,D. The spindle Ais formed with a raised portion, E, at its inner end, and with a collar or flange, F, just in rear of said raised portion.

G represents the axle'box, which is formed with an interior depressed portion, H, and with a further depressed portion, I, adjacent thereto and corresponding to the raised portion E and collar F, respectively. A washer, J, is placed against the shoulder of the dcpressed portion I, and against which the collar or flange F bears. The inner side of the axlebox is provided with a circumferential groove, q, formed upon the inner side of the depressed portion H, and also with an interior horizon tal groove communicating with the groove a.

[The spindle A is formed with an oil Clltill her or reservoir, the opening (I of which is formed with a screw-thread to receive a screwthreaded pin, 6. This oil-chamber c is out diagonally through the axle-spindle, so that While the opening to the same is outside or beyond the end of the axle-box, the outlet is 4,5 on the under side of the spindle and within the axle-box, and is so situated as to feed the lubricant into the groove a, and from thence it flows to the groove b, and by the revolution of the axle-box the spindle is thoroughly ln- 5o bricated.

K is a nut, which is formed with a flanged portion, f, and a collar, g. A washer, h, is placed within said collar, and bears against the flanged portion 9. This nut is adapted to 5 5 receive the screw-thread ed end of the spindle, the collar h embracing or inclosing the end of the box, thus preventing any dust or sand from entering the axle-box.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The herein-described axle A, provided with adiagonal oil-passage, c, and having a longitudinal groove, 0, in combination with an axlebox, G, provided with an annular groove, a, and a longitudinal groove, said groove a. reg istering with the groove Z), whereby the axle is lubricated, substantially as set forth.

In testimony thatI claim the foregoing as my own Ihave hereto affixediny signatnrein presence of two witnesses.
